Anew pollshows President Obama holding large leads over Republican challenger Mitt Romney in three key battleground states - Ohio, Florida and Pennsylvania.
The Quinnipiac University/CBS News/New York Times poll released Wednesday has Obama up by 10 percentage points in Ohio - 53 percent to 43 percent for Romney.
In Florida, Obama leads Romney with 53 percent support to 44 percent; and, in Pennsylvania, the president has a 12 percentage point lead - 54 percent to 42 percent for Romney.
No one has won the presidency since 1960 without winning at least two of these three states.
Voters in all three states say Obama would do a better job of handling the economy. In Ohio, 51 percent say Obama is better equipped to deal with the economy, while 45 percent choose Romney.
"Gov. Mitt Romney has had a bad week in the media and it shows in these key swing states,'' said Peter A. Brown, assistant director of the Quinnipiac University Polling Institute.
The upcoming presidential debates, Brown said, "may be Romney's best chance to reverse the trend in his favor."
From Sept. 18 through Sept. 24, Quinnipiac surveyed 1,162 likely Ohio voters. The margin of error is plus or minus 2.9 percent.
